Application led February This invention relates to a device adapted tobe used with a tractor when the tractor is operating in a corn or grainlield. Tractors, such as the well known llordson tractor, are nowcommonly used to draw corn pickers and other machines adapted to harvestthe corn or other grain. lWhen the corn is down, more or les" that is,the stalks have fallen over and the tractor draws the corn picker acrossthe field longitudinally of the rows ot corn a great many stalks whichhave fallen down are run over by the tractor wheels and are notharvested or operated upon by the picker so that a great deal of grainis lost. Y

lt is an object ot the invention to provide a lifted for ythe fallenstalks, which lifter is secured to the tractor and has a shoe or litingniember at one side et and in advance of the tractor which graduallylifts the fallen stalks and brings them into position to be effectivelyacted upon by the picker or other f harvester.

lt is a further object of the invention to provide a lifting device incombination with a tractor, which lifting device has a swinging arm orshoe at its "forward end connected to an upwardly inclined guide membervsecured at longitudinally spaced points to the tractor.

lt is another object oit the invention to provide a device as set forthin the preceding paragraph, in which the guide is pivotally connected tothe tractor, preferably to the Vrear wheel housing together 'with ineansfor raising the guide and said shoe at iront end, which means is adaptedto be readily operated by the driver of the tractor.

lt is more specitically an object of the invention to provice` a liftingvdevice coinprising an upwardly inclined shoe adapted to be disposedV infront of and at one side of the tractor, which shoe is connected to anupwardly inclined guide suitably secured to the tractor having a topsuri'iace and a vertically disposed side surface, saidV guide having aroller adjacent the forward end of its top surtace and in the rear ofthe front tractor wheel over which ears of corn are adapted to ride asthey move upwardly on said guide.

rl`hese and other objects and advantages oi the invention will be 'fullyset forth in the following description inade in connection withthevaccoinpanying drawings in which like reference characters reiter tothe saine parts throughout the diiierent views, and in which,

Referring to the drawings, a tractor of the well known small type isillust-rated, ot which it will only be necessary to consider the lirontwheels 6, the rear wheels (3a, the rear wheel housing or :tender 6, theengine casingGC, traine 6d and the steering wheel (Se. ln accordancewith the present invention, a litting device iior grain stalks, such ascorn stalks, is provided having a lifting shoe or arin 7 having asomewhat curved and substantially sharpened point 7lL at its lower end.lWhile the arm 7 may be made 'of various materials, in the embodiment ofthe invention illustrated, it is shown as made ot' wood and having a.pointed portion 7 covered with a metal strip 8. rllhe arm i" inclinesupwardly and rearwardly toward Aits rear vend and is hingedly connectedat saidend by the hinge 9 to the lower end of an upwardly and rearwardlyextending guide ineniber l0. rlhe arni can thus swing upwardly and itsposition relatively to 'the guide l() is normally determined by a yokell embracing the lower side of the ineiiibei' l() and carried on arm llextending iorwardly and secured at each side ot' the arin 7. Ylllheguide member 10 extends at one side oi the iiront wheel 6 and, at somedistance in the rear of said wheel, has an upper preferably flat portionl0 secured and supported at its inner end by another bar 10b. A rollerl2 is disposed adjacent the forward lower end ot the portion 10a havingits top surface substantially i'iush with said portion, which roller isjournaled on a headed and nutted bolt 13 extending between and throughthe members l() and 10b. A bracket 14; is secured to the underside ofmembers 10* and l0" and extends to the tractor frame 6d. One of thebolts which secures the engine casing or crank shaft casing 6C to thelower part ot thecasing or rainevd is renioved and a longer bolt '15inserted in its place.

rlfhis bo-lt 15 is provided with nuts 1(3- above v lsho wn aspivotallyconnected to the axle hous lngvl bv the hinge 17. fitthe topothousing 6b, a short distancevbeyond the center thereof, brackets 18 aresecured having journaled therein a crank shaft 19 having at its innerend the upwardly extending handle f portion 19a and at its-outer end theportion '19h 7p' qu.. 15' 1 .if ,117

i u .ic atcci por ion ias` a noiirontai y extending portion -19on whichis` iouinaledr a grooved roller 2O held in place by a split key 21.rllhe roller 20 isadaptedfto engage the upper rear end of portion 10a,said portion extending into the groovein said roller. 1t will beunderstood that in the invention, as illustrated, the portion vl0extendsy alongthe side of the wheel housing Gl. rlhe WideliOri- Zontallydisposed portion l()n terminates at the hinge 17.

ln operatiomthe tractor will be hitched to a corn picker and'will drawlthe'piclter along the rows of corn. Asthe tractor wheels move vat-oneside oi' `the outer 'row-being operated upon by the picker, the wheels 6will run closely adjacent said row, as will also the wheel 6a. rillhelitter arni or shoe 7. rtravels along in liront ot' tractor-quite closeto 'the ground. Anyfstalks which have fallen over vor have becoine'bentover will be engaged by the arm 7 which will pass thereunder and saidstalks will gradually bev raisedas the tractor advances and willlslideup on the arms i 7 and onto the guide 10. There is considerable roombetween the meinbcr 10- and the' liront wheel and any ears of cornonftlie stalk can readily pass therebetween. yHowever,l as the ystalksare raised higher, there is danger that ythe ears'will be stripped'therefrom' as they approach the rear part of the tractor. For' thisreason," the roller 12 is provided. As the ears pass upwardly andrearwardly along member lOtheywil-l engage the roller12 which revolvesvery easily and will ride up over said roller and onto the top portion10u of' the litter. 'The ears will thus be gently raised and lepton thestalksand gaged by the picker which follows 4closely adjacent the member10C. The ears swing to the outside of the verticali member- 10c so thatthey pass very ei'fcctively tothe picker or -huslein l/Vhen the tractoris to be turned, or

it is not desired to .use-the picker, the operator reaches' lever'19awhich is disposed in convenient position to the tractor seat and pullsthe lever rearwardly. rlhis depresses the arms 19b androllerQO and the:trent end oi the guide is swung up about the hinge 17,

lthe' bracket 141 moving upwardly .on the bolt 15. l'llhe arm 7 is'thus'considerably elevated and is out 'of the way of obstacles on fthe iground, while'theitractor vis beingturiied. and maneuvered.

From the above? description itv isseen tliat `.ipl'ilicaiitliasiprovided a .i very simple-.and

The stalks and ears.are very eil'iciently delivered to the corn picker. vrjhisdevicehasbeenused by quitennuniber or 'farmers in harvesting corn andthe same has saved from threeito twelve baskets ot corn in every loadhuslred. This corn would ordinarily be lost. "The ylitter works veryreilfectively either onl smooth vor` `rough ground.

Another advantage of applicantsdevice is :thatfwhenthe saineis used onthe :tractor a straight liitchmay be used-to the pickerand hitch in anattempt to keep the Ytractor away from the corn.

:The device ris quite simple and canbe inexpensively constructed andinstalled. The saine effects a great'saving and has great` .utilitydnuseand constitutes'aldecided advance in the art. Y

lt will, of course, be understoodfthat various changes may be made inthe form, details, arrangement Vand proportions ot the parts withoutdeparting from the yscope of applicants -rinventiom which, generallystated, consists in a device capableof carryving out the objectsiabove,set forth, in :the
